Make

• Open a terminal and get into the embedul.ar framework main directory, for example, “cd ~/embedul.ar”.
• Run a build with default parameters using make: “log_hello_world” example for the “native_hosted” target (your PC).

The output from make should resemble the image on the left. Last line should read “[LD] build/binary/native_hosted/gcc/debug_generic_O0/embedul.ar.elf” which implies the executable is now built.

Compilation database

Some integrated development environments consult a compilation database stored in the “compile_commands.json” file to learn how the compiler built the source code and to highlight code accordingly. A tool called Bear intercepts Make commands and creates that database. Therefore, we recommend using “bear” when building the code, as follows:

The command builds normally, generates the same output as before, but also updates the compilation database.

Running the example

The embedul.ar framework stores each build inside a “./build” directory containing further sub-directories representing build parameters: compiler, platform, processor core, debug information or optimization level, etc. Since make already knows this information, it is easier to call make itself to execute the right program, as follows:

You should see output resembling the sample image on the left.
Note that “make run” works for the “native_hosted” target only.
